_property _DataFrame.values

返回DataFrame的Numpy表示，仅返回DataFrame中的值，轴标签将被删除。
建议使用：DataFrame.to_numpy()

Example

import pandas as pd
df = pd.DataFrame({'site':['google', 'baidu', 'wiki', 'pandas'],
                    'age':[18, 39, 22, 45],
                    'price': [1.0, 2.0, 3.0, 4.0],
                    'color': ['red', 'black', None, 'red']}, index=['first', 'second', 'third', 'forth'])
df.values
-------------------------------------------------------
array([['google', 18, 1.0, 'red'],
       ['baidu', 39, 2.0, 'black'],
       ['wiki', 22, 3.0, None],
       ['pandas', 45, 4.0, 'red']], dtype=object)
